What is on line 71?  That doesn't look like the example script you 
posted originally.

.profile is not a shell.  I don't think the file has anything to do with
it.  Either bash is your login shell or it isn't.

bene at beacon:~$ cat .profile
HST=foobar
hst=${HST:0:3}

(logout, login again, no error)

bene at beacon:~$ lsb_release -d
Description:    Ubuntu 8.10
bene at beacon:~$ echo $HST
foobar
bene at beacon:~$ echo $hst
foo
bene at beacon:~$ echo $BASH
/bin/bash
bene at beacon:~$ echo $BASH_VERSION 
3.2.39(1)-release

So if it's not working, then you're not running bash.  This seems to be 
the conclusion you've come to in later emails.
